As your mother used to say, “A moist mouth is a healthy mouth.” Well, maybe she didn't — but it's still true. Without the constant flow of saliva, your teeth and gums would be less healthy.

That's because among its many functions, saliva helps keep the mouth from becoming too acidic. Just after eating, your mouth's neutral pH level tips to the acidic side of the scale. Acid is enamel's number one enemy, and it takes little time for it to begin dissolving mineral content. But in thirty minutes to an hour, saliva neutralizes the acid; it also helps restore some of the enamel's minerals.

Without adequate saliva flow, acid quickly gets the upper hand. In time, this can greatly increase your risk for dental disease. And for many people, inadequate saliva — dry mouth — is a chronic problem.

There are a number of reasons why. Salivary glands may not produce as much in our later years. In addition, as we age, we may begin taking more medications, some of which can cause dry mouth. Treatments for certain kinds of systemic diseases, particularly cancer, can also inhibit saliva or even damage salivary glands.

If you feel your mouth is continuously dry, make an appointment to find out the cause, which will determine the best course of action to alleviate it. If it's related to your medication, we'll see if there's an alternative. If not, you may need to drink more water when you take your medication and more throughout the day.

There are other things you can do as well. Reduce your intake of acidic foods or caffeinated beverages. Run a cool-air humidifier at night to keep your mouth and nose membranes moist. And you can also try saliva stimulants available by prescription or even over the counter. Chewing gum with xylitol (an alcohol-based sugar) has also been shown to stimulate saliva flow.

Above all, be diligent about daily brushing and flossing and regular dental cleanings and checkups. Keeping a watchful eye will help ensure dental disease doesn't take advantage of your dry mouth.
